摘　　要：A chiral complex of (R,R)-Pd was prepared by reaction of optically pure (R,R)-bis(pyrrol-2-ylmethyl-eneamino) cyclohexane ligand with Pd(OAc)2·2H2O under the base condition at room temperature. The weak intermolecular C-H···Pd interaction was found to be responsible for the homochiral M helix for-mation of the neutral,chiral,mononuclear (R,R)-Pd in the crystal packing.A chiral complex of （R,R）-Pd was prepared by reaction of optically pure （R,R）-bis（pyrrol-2-ylmethyleneamino） cyclohexane ligand with Pd（OAc）2.2H2O under the base condition at room temperature. The weak intermolecular C-H...Pd interaction was found to be responsible for the homochiral M helix formation of the neutral, chiral, mononuclear （R,R）-Pd in the crystal packing.
